VIBRATING CIRCUIT-BREAKER.

Specification of Letters Patent.

Patented Mar. 24, 1914.

Application filed June 17, 1910. Serial No. 567,451.

To all whom it may concern:

Be it known that I. PAUL M. RAINEY, a citizen of the United States, residing at West Hoboken, in the county of Hudson and State of New Jersey, have invented a certain new and useful Improvement in Vibrating Circuit-Breakers, of which the following is a full, clear, concise, and exact description.

This inyention relates to automatic vibrat vibratory movement until the normal rate is attained. 4

With this. improved device the temporary short closure of the circuit, as in depressinga button to signal, is effective to transmit current impulses having the predetermined, necessary, maximum electromotive force and desired frequency. The result is attained by substituting a device employing air friction as a regulating means in place of inertia due to mass. To this end the vibrator is provided with an armature in the form of a long broad vane supported at one end and passing intermediate its ends through the field of force of the induction coil, the circuit of which the said vane is adapted to intermittently open and close.

The accompanying drawings illustrate the invention.

Figure 1 is a front elevation of the vibrating contact; Fig. 2 is a side elevation, partly in section, showing an induction coil and its two electrical contacts forming the vibrating circuit breaker.

The induction coil 11 has the usual primary coil p, and secondary coil s. The electrical contacts forming the circuit breaker for this induction coil consist of an electrical contact a in the form of a spring fixed in position by screws 5, while the vibrating contact a is suitably insulated, as at q, and held by the same screws 1;. This vibrating contact a is novel and consists of a thin plate of magnetic metal, such as sheet iron. arranged vertically in the plane of the and extending within and through the field of force of said pole piece. The plate a is designed and constructed to have comparatively extended superficial area with small mass or gravity, the object being to so construct the fan or vane that while it will reach its normal rate of vibration immediately the air presents resistance thereto and affords regulation of its vibrating movement. It results from this construction that uponclosing a circuit through the primary winding 79 for a brief interval only. the vane 4; starts into its approximately normal rate of vibration quickly; and yet, due to the retarding action of the air upon the lloroad vane, this period may be relatively ow. I

What I claim and desire to secure by Letters Patent is:

1. An interrupter comprising an induction coil, an armature, a support for said coil and armature, said armature being in the form of a long broad vane anchored at one end to said support and passing through and beyond the field of force of said coil. and a circuit including said coil adapted to be opened and closed by said armature in 1ts movement.

2. An interrupter comprising an induction coil, an armature, a support for said coil and armature, said armature being in the form of a long broad vane anchored at one end to said support and passing near 11's anchored and through and extending beyo-nd the field of force of said coil, and a cir- PAUL M.
